, Referring now to the drawing in detail ,numeral -1 designates athIe dilator comprising an inner rubbentube 2 attachedto a sleeve' 3. 7 The. sleeve :is provided with a longitudinal (boredinwhiohfits alpipe 5 leadingrto a rubber .;hose 6. At the free-endof the hose isa bulb :7 sfQI creating air pressure within the inner tube 2. tSurronndingthe said tubeis'a set of :resilient iwire guards :8. The-upper part of the guards are embedded/in aisolid cap.9 rwhilethezbottom ends are bent outwardly and embeddedin .a soft rubberbase 1-0. 'As'noted in Figurefi soniezofgthe wireguards arelon'ger '3 thanothers; .thleshorter ones: being placed beitweentherlongones. i t

Goveringithe assemblyxoi wires, andrthe-top and side of the base llS an outer rubber gtube 11. Atlthebottomofrthebase is a guide12 1; for :.the cables .13. The" guide comprises a :flat .member. lhenga'ging the :bottombf Lthe base and two tubularnnenibers; 15' and 1:6 .at the .sides through. which looselyjpass the said cables 13. p T *1 The inner a tube is positioned 1' in place iby r-th solidzrubbennipple117 fitting in the hole :18 .ofithemase 10. .Betweenthe outerrtuberlfl -and.-the.asse nbly.ofwireguards 8 is. a pliable ring lfil-made ofnonstretchablematerial and 100 of a given diameter for a purpose to be later described. The sleeve 3 is provided with a bottom flange 20 having a set of holes therein in which pass the stitches 22 for the purpose of stitching the said sleeve to the base 10 The dilator is attached to a belt 23 which is worn around the waist of the patient- Numeral 24 designates a slidable front sleeve fitting on the belt to which is attached a pad 25. The attaching means comprises a button 26 sewed on the pad and fitting into a-hook'27 suspended from the sleeve 24. Tied to the corners of the pad is the front cables 13. 'At the rear of the belt is another sleeve 28 to which is attached the rear set of cables 13. Numeral 29 designates a set of short sections of rubber tubes covering the cables and adapted to protect the patients skin from being chafed or otherwise injured by the bare cables. I i

The operation ofthe device is asfollows: The dilator is first placed in the rectum and air pressure created in the inner tube 2 by repeatedly contracting the bulb 7. The bulb is of standard construction and includes a distend also and thereby expand and enlarge the membrane of the rectum. v

The ring 19 being of-a certain measured diameter and non stretchable will limit the stretching of the dilator at 30 as shown in Figure 6. It is very important not to have the dilator stretch too much at this point otherwise the mouth of the rectum is liable to be ruptured. l/Vhen the dilator is in a non distended position the ring 19 being normally larger in diameter than the outer tube will be gathered between the wire guards into a smaller diameter.

Thepurpose of providing means to attach the device to the body of the wearer is to enable the patient to be treated without any interference and while engaged in his regular business activities. The device can be carried around'and worn'without any discomfort to the patient. vThe dilators can be made of va rious sizes to suit the needs of the patient.

Having described my invention, I claim:
